Wait, exactly how does osmosis work? Because simple diffusion down concentration gradients doesn't make sense...
Why the fuck do they obfuscate the issue by saying water 'wants' to do anything ffs.

Everything 'wants' to reestablish equilibrium
Diffusion itself is the movement of a solute from a high concentration to a low concentration. This is due to there being a higher chance of the solute particles colliding in the high concentration areas and thus, causing the solute to 'spread out' more and move to the lower concentrated areas.
Osmosis is exactly like diffusion, but instead of solute particles colliding and moving to lower concentrations, there's a semi-permeable membrane which prevents this from occuring. Therefore, instead, the water particles, acting similarly to the solute in diffusion, have a higher chance to collide in higher concentrations and thus, 'spread out' (diffuse) across the semi-permeable membrane and move towards the area of lower concentrations of water molecules.
it doesn't 'want' to do anything, the random movement of particles just means more would pass through a membrane from an area of higher concentration till the density is equal on both sides, where the movement of particles over the membrane is negligible since roughly the same volume would do so

Wish there was more, but it just does desu

it's literally just 'particles collide more when they're closer together'
they'll end up moving in the direction they're not being blocked from going
so there's less particles to stop their movement in the direction in the gradient
so they'll go that way
I fail to see what you find hard about this
it's middle school physics
